Calculate how much disk space (in sectors, tracks, and surfaces) will be required to
store 300,000 120-byte logical records if the disk is fixed sector with 512 bytes/
sector, with 96 sectors/track, 110 tracks per surface, and 8 usable surfaces. Ignore
any file header record(s) and track indexes, and assume that records cannot span
two sectors.

It will be great if you could explain the answer to me. :)

Answer:

name is a reserved word in JS and cannot be used as an identifier

Explanation:

From the group of answer choices provided the only one that may be a problem would be using the word name as a parameter. Although name is not a reserved word per say in JS it is in HTML, and since JS targets HTML it could cause some errors. This however does not prevent this code from running correctly. JS does not require semicolons anymore, and the opening and closing braces for a body of code does not need to be on their own lines. Also, variable names are not Strings and do not need to be inside quotes, even for console.log()

Answer:

PAN

Explanation:

For wireless devices like laptops, tablets, wireless desktops, and cellphones to communicate, a wireless LAN normally has a Wi-Fi router or wireless access point. A wireless LAN is essentially a LAN that doesn't use cables. Thus, option B is correct.

The computer network that links computers and other devices within a specific person's range is known as a personal area network (PAN). PAN stands for personal area network and gives a network range within a person's range, often within a range of 10 meters (33 feet).

A PAN is a network that primarily serves a tiny space, usually a single small room. It allows computer devices to share data and information with other nearby computers.

Therefore, Whereas in LAN, computers are connected via a network over a short distance, such as within a building, or in a single computer network made up of several computers.

Answer:

D. 5

Explanation:

If the variables original value was 5 then the value that will be printed is 5. This is because the variable is being passed as a parameter into the function and 5 is being added to the parameter value, not the actual global variable outside. Therefore, in order for the adjusted value to be printed then that new value that is returned by the function needs to be saved in a new variable. This can be seen in the example code below.

Answer:index(E3:H12,1)

Explanation:

Answer: =INDEX(AcademicGroups,1,1)

Explanation:

Use the INDEX function (fx) button and you will be provided two different arguments to choose from.

Select the argument: array,row,num,column,num

In the Array section, click the up-arrow and then highlight the range A2:G12 (this is the AcademicsGroups table).

In the Row_num section, enter the number 1

In the Column_num section, enter the number 1

The statement that is false is: The boot process is the process for powering off a computer, which is the second option. The boot process is actually the process of starting or powering on a computer, not powering it off.

The boot process refers to the sequence of events that occur when a computer is powered on or restarted. It is the process of starting up the computer's hardware and loading the operating system into memory so that it is ready for use. During the boot process, the computer's firmware (such as the BIOS or UEFI) performs a series of checks and tests to ensure that the hardware components are functioning correctly. It then searches for the operating system on connected storage devices, such as the hard drive or solid-state drive, and loads it into memory.

Answer:

Explanation:

There are all sorts of possibilities for, say, inserting new technologies into existing processes. But most of these improvements are incremental. They are worth doing; in fact, they may be necessary for survival. No self-respecting airline, for instance, could do without an application that lets you download your boarding pass to your mobile telephone. It saves paper, can't get lost and customers want it.

But while it's essential to offer applications like the electronic boarding pass, those will not distinguish a company. Electronic boarding passes have already been replicated by nearly every airline. In fact, we've already forgotten who was first.

Explanation:

Since there are two microservices that need to communicate with each other without holding up a thread on either end, the communication framework should be used is a RESTful architecture for both, send the ID through a POST, and ping the service with a GET until a response is available.

REST is a software architectural style which is used in defining the set of rules that be used for the creation of web services. The REST architecture allows requesting systems to be able to access and manipulate web resources.

Answer:

Explanation:

Threads allow an applications to run faster because they allow various tasks to run at the same time instead of doing one at a time and having to wait for one to finish before starting the next task. However, if too many threads are running at the same time, or a thread has a very large task or requires another task to finish before finishing its own then this can drastically impact performance. Mainly because too many resources are being used at a single moment. The following code is a small example of how threads work in Python.

import threading

import time

def thread_function(name):

   print("Thread {name}: starting")

   time.sleep(2)

   print("Thread {name}: finishing")

thread1 = threading.Thread(target=thread_function, args=(1,))

thread1.start()

time.sleep(1)

thread2 = threading.Thread(target=thread_function, args=(2,))

thread2.start()

thread2.join()

Answer:

The program in Python is as follows:

A = int(input("A: "))

B = int(input("B: "))

C = int(input("C: "))

while A<=0 or B <= 0 or C <= 0:

   A = int(input("A: "))

   B = int(input("B: "))

   C = int(input("C: "))

print("Valid inputs")

Explanation:

Get input for A, B and C

A = int(input("A: "))

B = int(input("B: "))

C = int(input("C: "))

The loop is repeated until inputs for A, B and C are above 0

while A<=0 or B <= 0 or C <= 0:

Get input for A, B and C

   A = int(input("A: "))

   B = int(input("B: "))

   C = int(input("C: "))

Print valid inputs when user inputs are correct

print("Valid inputs")
